Re: [TCML] VTTC grid feedback coil -> HV Probes

Hi Steve and all-
I have several new 1000:1 15 Kv 5 MHz BNC switchable 10M ohm for multimeter / 1M ohm for 'scope industrial-grade probes made in England. I'll sell them to list members for $35 plus actual shipping from Austin TX.

Hi Chris,

I still think my feedback coil has too many windings, but I am not going to remove any more turns until I can actually measure the grid voltage. I don't like doing things like this blind without some measurement to assess whether I am doing good or bad. I have a very good 100 MHz BW digital oscilloscope but I do not have a high voltage probe, therefore I am getting ready to order one.

Hi Steve,

Sounding better on your grid winding. I also agree lowering this closer to
primary if possible is better also. As you already know, should be better
for eliminating possible shorts.

Your PFC currently for how your coil is running now sounds good. This
should also help you since you are taking this portable coil around with
you. You may not always be able to plug into 20A 120V line. Could be 15A ,
especially if an older place as you know, should be able to just run I
think with current PFC.

Sounds like a good idea to coat a bit heavier, again since you are taking
this around. Sounds like you are thinking about the temperature extremes it
is possibly going to see during transport. Then running inside, then back.
If it was me I would also feel better about doing this.

Chris
